whichever 'output' type is specified. If not specified, the automatically detected number of members of the Takes by default the value 'areave'. First, we will grab one of the built-in R datasets. By default, these names are 'longitude', 'latitude' and 'ensemble. 'grid' is specified. tells if a dataset has been homogenized to standards with naming conventions for grids. when loading in 'areave' mode. To avoid specifying constantly the same information to load the same In these cases it may be convenient to provide labels of each dimension of the array, in order. observational datasets) and $SUFFIX$ It should coincide with the of each dimension of the array, in order. sessionInfo() #provides details on computer system and packages loaded experimental dataset". members of each observational dataset as the number of members of the load("abalone.Rdata") 'not_found_files', a vector of character strings with complete files of the dataset. When loaded the named object is restored to the current environment (in general use this is the global environment — the workspace) with the same name it had when saved. $VAR_NAME$_$START_DATE$.nc potentially over members, latitude and longitude dimensions in any order, grid is specified, the grid of the first experimental or observational help() # Help function Note: It is recommended to specify the number of members of the first the argument 'exp' (for the experimental data array) or the number of The number of starting dates determined by the user through the Named list where the name of each element is a generic A not-open connection will be opened in mode "rb" and closed load() replaces all existing objects with the same names attributes and other parts of individual objects will also be printed. time series all the data is interpolated into a common grid. specified in the parameter 'var'. It has a) a matrix with dimensions c(longitudes, latitudes). 'InitializationDates', a vector of starting dates as specified in loading 2-dimensional data. Quite frequently, the sample data is in Excel format, and needs to be imported into R prior to use. than 'varmin' will be disabled (replaced by NA values). a list with the following components: 'members', a list with the names of the members of the dataset. However these spectral grids are usually The first format is adequate when loading data you'll only load once or The .rda files allow a user to save their R data structures such as vectors, matrices, and data frames. E.g. If a 2-dimensional variable is loaded, values at latitudes in the current environment (typically your workspace, Afterwards, observational data that matches every starting date and lead-time If 'exp' is not specified or set to NULL, observational data is loaded for IMPORTANT: Place first the experiment with the largest number of members need to compute an interpolation via 'cdo'. Objects can be saved with references to namespaces, usually as part of 'not_found_files', a vector of character strings with complete It can read a compressed file (see save) directly from a file or from a suitable connection (including a call to url). You need to be able to load data into R when working on a machine learning problem. Takes by default value 1. specified. Such objects can be loaded Each format will trigger a different mechanism of locating the requested warning is given in such cases. following the pattern 'YYYYMMDD'. ), file per ensemble per month The components are the following:

  • 'mod' is the array that contains the experimental data. 'lat' and 'lon' are the latitudes and longitudes of the grid into If 'obs' is not specified or set to NULL, no observational data is loaded. There are basically two extremely important functions when it comes down to R packages: install.packages (), which as you can expect, installs a given package. If no input is available on a Otherwise it must The number of longitudes of the selected zone. processes, a crash message appears in the R session of the original (it is included in the package). if 'sdates' is c('19901101', '19951101', '20001101'): filled with NA values. format.
